Cooler Master Mobius 120 OC High Performance Interconnecting Ring Blade Fan, PWM Fan Speed Toggle, Metal Motor Hub, Double Ball Bearing for PC Case, Liquid and Air Cooler (MFZ-M2NN-32NPK-R1), Black

Why did you pick this product vs others?:Good fan, great price, compatible with MSI Mystic Light app. Wish it worked with ICUe app but it's a great buy

Works well

Great product easy to install didn't need a hub.

I put this 120 OC on a single radiator to replace a slower case fan blowing up through the top screens. Running this at 1500 rpm pushes less air but it really picks up by 2500 rpm. By 3200 rpm you know it's working by the sound and air blowing. Remember, there is not that much benefit going from 2500 to 3200 rpm unless it is a last resort to prevent overheating. It has good pressure and flow at high speed but does make some noise. I didn't use the rpm switch since it's on PWM speed control. And I have no idea how to use the rubber straps that came with it. Maybe they work for case mounting and not radiators.Noise at full speed appears to be the same 41dB as Noctua 3000 rpm fan which is rated 110 cfm VS 88 cfm for this OC. Static pressure is 7.63 VS 4.75 mmH2O.

A amazing fan that helps keep my cpu in the mid 50c and that's playing call of duty black ops 6 get this fan it's fast was easy to put on the cpu cooler functions great and super low noise levels

Mechanically, they work well.However, if you look at the picture closely, the fan blades and the corners are blue. I didn't look closely enough and thought I was getting black. That blue does not match the 360 AIO cooler they also sell, so my symmetry is goofy.Also, you'll need fan extension cables. The little pigtails are not about to reach any fan controller or MB you have.Also, if you are mounting them to a >3mm surface (like the side wings of a MasterFrame700 case), the included screws are too short and don't bite, so I had to go through-bolts.They move a lot of air, but this install is a complete mess, and at $40 a pop, come on. I've purchased $4 fans with nice long cables to them, and/so a return is kind of tempting.Remember, the ugly label side is the blow side. Pretty-side is suck.

Worked for my needs.

Had 2 fans for the last 6 months. They are pretty quiet, move a ton of air, RGB looks great and they seem to be high quality.
